Half Dome is now 2,400 tons smaller

 

A rockfall occurred on the face of Half Dome in Yosemite National Park sometime during the night of Thursday to Friday, July 2 and 3. The exfoliating slice of granite that fell is estimated to be about 2,400 tons. No injuries occurred due to the rockfall.

A Yosemite spokesperson said that a rockfall this large happens about once a year on the precipices that surround Yosemite Valley. The hike to the top of Half Dome and the trail around Mirror Lake are not affected and remain open. 

The slab fell from a portion of the popular “Regular Northwest Face” climbing route. Climbing rangers have assessed the area and determined that there is loose rock but did not close the route. 

They are warning climbers to  use extreme caution if climbing in this area. Additionally, climbers and hikers should not linger in the obvious rock debris at the base of the Regular Northwest Face route.
